Nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvekugadzira maindasitiri zve crane kumhanya mutemo kuita, yakajairika yechinyakare crane kumhanya yekudzora nzira senge winding rotor asynchronous mota rotor series resistance regulation, thyristor stator voltage regulation speed regulation uye cascade speed regulation ine zvinotevera zvinokanganisa: the winding rotor asynchronous mota ine muunganidzi mhete nemabhurashi, ayo anoda kugara achigadziriswa. Kukundikana kunokonzerwa nekuunganidza zvindori uye mabhurashi zvinowanzoitika. Pamusoro pezvo, kushandiswa kwenhamba yakakura yerelays uye macontactor anokonzeresa kuwanda kwekuchengetedza-pa-saiti, kutadza kwakanyanya kweiyo yekumhanyisa regulation system, uye hurombo hwakakwana hwehunyanzvi zviratidzo zveiyo yekumhanyisa regulation system, iyo isingachakwanise kusangana. izvo zvakakosha zvinodiwa zvekugadzirwa kwemaindasitiri.
Iko kushandiswa kwakakura kwe AC kusiyanisa frequency regulation tekinoroji muindasitiri yeindasitiri inopa mhinduro nyowani kune yakakura-yepamusoro-yemhando yekumhanyisa kudzora kwema cranes inofambiswa ne AC asynchronous motors. Iyo ine yakakwirira-yekuita yekumhanyisa kudzora zviratidzo, inogona kushandisa squirrel cage asynchronous mota ine yakapusa chimiro, yakavimbika kushanda uye nyore kugadzirisa, uye inoshanda uye inochengetedza simba. Yayo peripheral control circuit iri nyore, basa rekuchengetedza idiki, kuchengetedza uye kutarisisa mabasa akakwana, uye kuvimbika kwekushanda kunovandudzwa zvakanyanya kana zvichienzaniswa neyechinyakare AC yekumhanyisa regulation system. Naizvozvo, kushandiswa kweiyo AC inosiyana frequency yekumhanyisa regulation ndiyo huru yekuvandudzwa kwecrane AC yekumhanyisa regulation tekinoroji.
Mushure meiyo AC inosiyana frequency regulation regulation tekinoroji yaiswa kune cranes, kana ichienzaniswa neyechinyakare mhepo asynchronous mota rotor akateedzana kumhanyisa regulation system inoshandiswa zvakanyanya pamusika, inogona kuunza zvinotevera zvakakosha zvehupfumi uye kuchengetedzeka uye kuvimbika:
(1) Ma cranes anoshandisa AC inochinja frequency regulation tekinoroji ane mukana weiyo chaiyo chinzvimbo nekuda kwemakanika maitiro emota inofambiswa ne frequency converter, uye haizove nechiitiko chekuti mota inomhanya inoshanduka nekuremerwa kwechinyakare cranes, iyo inogona kuvandudza kugadzirwa kwekurodha nekuburitsa mabasa.
(2) Iyo inoshanduka frequency crane inomhanya zvakanaka, inotanga uye mabhureki zvakanaka, uye kuzununguka uye kukanganisa kwemuchina wese zvakadzikiswa zvakanyanya panguva yekumhanyisa uye kudzikisira panguva yekushanda, izvo zvinovandudza kuchengetedzeka uye kuwedzera hupenyu hwemakanika zvikamu zve crane.
(3) Mechanical brake inobatiswa kana mota ichimhanya yakaderera, uye braking yehoko huru uye trolley inopedzwa nemagetsi mabhureki, saka hupenyu hwebhureki remakiniki mabhureki hunowedzerwa zvakanyanya uye mutengo wekugadzirisa unoderedzwa. .
(4) Iyo squirrel cage asynchronous mota ine yakapusa chimiro uye yakakwirira kuvimbika inoshandiswa kutsiva inotenderedza rotor asynchronous mota, kudzivirira kutadza kwemota kukuvara kana kutadza kutanga kunokonzerwa nekusaonana zvakanaka nekuda kwekupfeka kana kuora kwemuunganidzi mhete nebhurashi. .
(5) Huwandu hwema AC contactors hwakadzikiswa zvakanyanya, uye dunhu guru remota rakawana kudzora kusingabatanidzi, kudzivirira kupisa kweanobatika macontact nekuda kwekugara uchivhiya uye kukuvadzwa kwemota kunokonzerwa nekupisa kweanobatika macontact.
(6) Iyo AC inochinja-chinja frequency regulation system inogona kuchinjika kumhanyisa kumhanya kwegiya rega rega uye kukwidziridza uye kudzika nguva zvinoenderana ne-on-saiti mamiriro, ichiita iyo inoshanduka frequency crane inochinjika kushanda uye kuve yakanaka pane-saiti inochinjika.
(7) The AC variable frequency speed regulation system is high-effects speed regulation system ine hupamhi hwekushanda uye kupera kwekushisa, saka inochengetedza magetsi akawanda kana ichienzaniswa neyekare yekumhanyisa hurongwa.
(8) Iyo frequency converter ine dziviriro yakakwana, yekutarisa uye yekuzviongorora mabasa. Kana yakasanganiswa nePLC kutonga, inogona kuvandudza zvakanyanya kuvimbika kweiyo inosiyana frequency crane electronic control system.
